A thermal transfer printer is a type of printer that develops labels and indicators by thawing wax or resin-based “ink” onto paper, tape, as well as also products like warm reduce tubes. Thermal transfer printers are recognized for their smear-proof images as well as resistance to fading and are particularly well fit for producing barcodes.
The main practical element of a thermal transfer printer is its print head, which extends the size of whatever tape or printing medium the printer is built to deal with. The thermal print head is made up of tiny home heating pins, each of which represents a single pixel (pixel dimension, as well as density, vary by printer– lots of portable designs range between 203 as well as 300 dpi, or dots per inch).
The key material used in Thermal transfer labels printing is wax or resin-based ink, which is packed right into the printer in the form of a bow: in a strong state, applied in a very slim layer to a backing of polyester film. This “ink” ribbon is drawn through the printer between the printing medium (paper or tape, as gone over earlier) and the print head.
The print head is managed by a microprocessor, which identifies which heating pins require to be activated in order to form a detailed image. From there, signals are sent out to the selected pins, causing them to rapidly warmth as well as cool versus the ink bow, melting as well as moving ink off of its backing movie and onto the empty tag surface area.
What is the distinction in between wax-based as well as resin-based thermal ink ribbons?
The outcomes might not vary much to the eye, but the reality is that all thermal transfer inks are not developed equal. Always be aware of the demands of your certain application before you choose which kind of transfer ribbon to use.
As a result of their clearly different characteristics, wax and also material usually can’t be interchanged, but in some cases, they’re actually incorporated right into a wax-resin crossbreed ink. Listed below, read a little extra regarding the traits of– as well as finest uses for– the 3 primary kinds of thermal transfer inks.
Wax thermal transfer ribbons are most generally utilized for printing onto paper tags. The photos they produce can last for many years, but not without security: wax-printed tags need to remain completely dry, and also are highly conscious abrasives, chemicals, and oils, which can put on or melt wax inks away.
Wax-resin substances function well with smooth – in addition to coated -paper tags. The wax-resin mix generates an extra polished picture, and while it still requires to be guarded against excessive moisture, it offers much more longevity than ordinary wax.
* Pure Resin:
Out of the three, the pure material is the most difficult thing you can publish a thermal transfer label from, however, it isn’t created for usage with paper. Resin-based thermal inks are crafted to fuse onto vinyl, polyester, and also polypropylene labels, and are extremely long-lasting.
Plastic tag/ resin bow combinations are made to weather the toughest atmospheres: they won’t fade in sunlight, can be submerged in water, and also– depending on the product– can be resistant to damage from oils and chemicals. Material is the “ink” of selection for aquatic, automotive, aircraft, industrial, as well as dangerous chemical applications
